Plasma Lost To LCD On Cost, Not Quality

Setup. In the 1960s, University of Illinois engineers needed a computer display that did not need the costly memory a TV's cathode-ray tube demanded. Donald Bitzer's team found that a sealed pocket of glowing gas kept glowing by accident after the voltage dropped, a real memory effect. Owens-Illinois licensed it in 1967 and shipped the first commercial plasma screen in 1971.

What happened. Plasma scaled into large, thin televisions through the 1990s and 2000s, competing against cheaper-to-shrink liquid-crystal displays. By 2006 the two looked similar in quality, yet LCD was already outselling plasma. "The most important issue was likely manufacturing: it proved harder to achieve high yields and low manufacturing costs with plasma screens than with LCD screens, possibly because manufacturers invested far more in LCD manufacturing than they did plasma." Plasma TV production had essentially ended by the late 2010s.

Where it stands. This is one writer's historical synthesis, not a peer-reviewed study, but it names companies and dates rather than giving opinion. It leaves open whether plasma lost on manufacturing economics alone, or whether LCD's investment advantage came from an earlier, harder-to-trace cost edge.

A Truthful Algorithm Now Assigns Doctors And Kidneys

Setup. Some markets cannot use prices to match supply and demand: a hospital residency slot, a school seat, a kidney, all go to a specific recipient rather than the highest bidder. Economists Alvin Roth and Marilda Sotomayor's 1990 book collected the theory built to solve this, the stable matching problem, where two groups each rank the other and need a pairing nobody can improve by swapping.

The finding. "The book's introduction discusses the National Resident Matching Program and its use of stable marriage to assign medical students to hospital positions, and collects the problems in economics that the theory of matching markets is positioned to solve." The underlying Gale-Shapley algorithm has a property that makes it usable in practice: reporting preferences honestly is each side's best strategy.

Where it stands. This is a textbook synthesis of established game theory, not a new claim, and it won a 1990 operations-research prize for organizing the field well. Its acknowledged limit is that real matching markets involving couples who want to be placed together can break the clean guarantees, a problem later research has only partly resolved.

Gender Means Power, Not Just Sex Difference

Setup. Historians had generally treated sex differences between women and men as a biological fact that explained itself, not something to investigate. In 1986, historian Joan Wallach Scott published a paper in the American Historical Review arguing that this habit missed the real work gender does in history.

The argument. "Scott then provides her own definition of gender in two parts: gender is based on the perceived differences between the sexes, but is also a way of signifying power differentials." On her reading, gender is a tool institutions use to allocate authority, so the history of male institutions, armies, parliaments, courts, is also a history of gender, whether or not women appear in it.

Where it stands. The paper's influence is well documented: by 2008 it was the most-accessed article in the American Historical Review's online archive, with over 38,000 views. Reception split sharply at first. One early critic called it "nihilism, presentism, ahistoricism, obfuscation, elitism, obeisance to patriarchy, ethnocentrism, irrelevance, and possibly racism," while others called it an instant classic, and it is now standard reading in the field.

ECONOMIC HISTORY · academic growth-theory book, Nobel laureates' praise · 2011

Falling Birth Rates Freed The Modern Growth Take-off

Setup. For nearly all of human history, better technology did not make people richer, since more food just let population grow until each person was back at subsistence, the Malthusian trap. Economist Oded Galor's 2011 book sets out a single framework explaining how humanity escaped that trap, and why some regions escaped centuries before others.

The argument. As technology improved, it raised the payoff to being educated, so parents invested more in each child's schooling rather than having more children. "Falling fertility released economies from the counterbalancing effects of population growth and, alongside the advance of knowledge and the rise of education, opened the path to sustained growth and modern prosperity." Galor frames this as a phase transition, a system stable for millennia crossing a threshold into a different equilibrium.

Where it stands. Nobel laureates Robert Solow and Daron Acemoglu have praised the book's ambition, and it has shaped later growth research. The theory explains the overall pattern well, but like most grand unified accounts, it is harder to use for predicting any one country's timeline, since it treats institutional factors as given rather than derived.

SOCIAL PSYCHOLOGY · peer-reviewed study · 2012

Wealth And Independence, Not Virtue, Shape Ethics

Setup. Psychologists have started asking whether social class changes not just what people can afford, but how they think. Growing up with fewer resources tends to force reliance on others, fostering what researchers call an interdependent self. Growing up with more resources allows more autonomy, fostering an independent self.

The finding. A 2012 study by Paul Piff and colleagues found "upper-class individuals engage in more unethical behavior than lower-class individuals," tied to their relative independence from others, more privacy, fewer constraints, and more resources to handle any fallout. A separate 2009 study by Kraus and Keltner found higher-class individuals show more visible disengagement, such as checking phones, during conversations with strangers.

Where it stands. This is an active research program, not one settled result, and "unethical" in these studies means specific lab tasks, like cheating in a game, rather than a global trait. The self-construal mechanism behind it, resource constraints shaping independence versus interdependence, is well supported and explains a related finding: lower-income households give a higher share of their income to charity than higher-income ones do.

Trusting Automation Makes Experts Miss Its Failures

Setup. Cockpits, hospitals, and nuclear control rooms added computerized monitors and decision aids to reduce human error. Automation bias is the finding that this can backfire: people favor an automated system's suggestion and discount contradicting evidence, even their own expertise, simply because a machine produced it.

The finding. In a 2005 study, air traffic controllers ran a high-fidelity simulation with an automated tool that flagged aircraft on a collision course minutes ahead. When researchers disabled the tool near the end of the test, "considerably fewer controllers detected the conflict than when the situation was handled manually." Separately, pilots given a false alert to shut off a working engine did so, despite insisting afterward they would not have.

Where it stands. This is a replicated applied finding across aviation, medicine, and the military, not one lab result. A 2007 study proposed automation stops being a net benefit once its reliability drops below roughly 70 percent, a specific but less certain number. Training reduces one error, acting on a bad alert, but not the other, missing a failure automation never flagged.

A Voting Board Gave Three Towns Zero Power

Setup. Many organizations split voting rights unevenly, corporate boards, weighted legislatures, the Electoral College, assuming a bigger vote share means more real influence. In 1965, law professor John Banzhaf devised a direct test: across every winning coalition, count how often each voter's vote actually decides the outcome.

The finding. Banzhaf applied this to the Nassau County, New York Board of Supervisors, where six municipalities held between 9 and 1 votes of 30, needing 16 to pass a measure. The three smallest municipalities, holding 5 of the 30 votes combined, never turned out to be the decisive vote in any winning coalition. "Banzhaf argued that a voting arrangement that gives 0% of the power to 16% of the population is unfair."

Where it stands. This is a proven mathematical result, not a contested claim, and it remains a standard tool for analyzing weighted votes in bodies like the European Council. Its real limit is the model underneath it: Banzhaf treated each vote as an independent coin flip, and a model based on how voters and blocs actually behave gives different answers.

Police Chose To Regulate Vice, Not End It

Setup. In the late 1800s, American cities faced a problem city governments still face: how to handle something widely viewed as immoral and dangerous, prostitution, tied then to syphilis, an incurable disease, when police lack the resources to eliminate it. Sociologist Joel Best's 1998 study traces how St. Paul, Minnesota, answered that question between 1865 and 1883.

What happened. Rather than attempt full suppression, St. Paul's undermanned police force chose a middle path. "Police also allowed for the toleration of several regulated brothels, but they must be seen to by officials of the law with the ability to arrest by means to maintain order." By 1880, the city had seven recognized brothels, and officers arrested roughly 14 madams a year, mostly to enforce licensing terms rather than end the trade.

Where it stands. This is a single documented case, not a general law, but the mechanism recurs wherever enforcement capacity is outmatched by the behavior it targets: institutions trade elimination for contained, licensed tolerance. The same logic shows up in modern vice zoning and in how cities handle drug markets they cannot fully suppress.

Rare Choices Reveal People, Common Ones Reveal Nothing

Setup. When someone picks one option over another, how much does that choice really reveal about who they are? In 1965, psychologists Edward Jones and Keith Davis proposed correspondent inference theory to answer this precisely: an observer can infer a stable trait from a choice only under specific, nameable conditions, not from the mere fact that a choice was made.

The argument. The key condition is what Jones and Davis called non-common effects. "The fewer effects the possible choices have in common, the more confident one can be in inferring a correspondent disposition." A student choosing one near-identical university over another reveals almost nothing distinctive about their motives, because the two options share too much. The theory adds that unusual, socially undesirable, or role-defying choices carry far more information than ordinary, expected ones.

Where it stands. This is the original 1965 theory, not a later replication, and it still anchors modern attribution research. Its own prediction, that people should discount choices made under situational pressure, often fails in practice: later studies show observers over-attribute scripted statements to true belief even when the pressure on the speaker is obvious.

A Flawed Study Method Still Beat The Market

Setup. In 1982, consultants Tom Peters and Robert Waterman published a hugely influential study of 43 "excellent" American companies, chosen partly by asking McKinsey partners who was "cool." The book skipped a basic scientific control: a comparison group of companies that did not thrive.

What happened. Management scholar Phil Rosenzweig later called this the halo effect: you cannot find the traits that cause success by studying only companies that already succeeded. Several of the 43, including Wang Labs and Xerox, performed badly afterward. Yet a 2002 Forbes analysis found the "excellence" companies as a group still beat the market: "the companies on the authors' list earned an average total return of 1,305%, or 14.1% annually," against 11.3% for the Dow and 10.1% for the S&P 500 since 1982.

Where it stands. The individual stock picks aged poorly, exactly as the halo-effect critique would predict from a study with no control group. The aggregate result did not, and neither the methodology nor its critics fully explain why. Read it as a case where a flawed research method still stumbled onto a real signal, not proof the method itself worked.

Toddlers Learn Better From A Trusted Character

Setup. Sesame Street characters speak straight to the camera, and kids often feel a one-sided friendship with them, a bond researchers call parasocial interaction. The open question is whether that felt bond does anything beyond entertainment.

The finding. In a 2011 study, researchers taught eight 21-month-old American infants to nest a set of cups in order, using one of two on-screen characters: Elmo, instantly recognizable to American toddlers, or DoDo, popular in Taiwan but unfamiliar in the United States. "Children were better able to learn from the socially meaningful character (Elmo) than from the character who was less easily recognized (DoDo)." A later study closed that gap by personalizing the unfamiliar character, giving toddlers a doll version to name and play with first.

Where it stands. The sample is small, eight infants, typical of lab studies run on toddlers this young, so the size of the effect should be held loosely. The direction fits a broader pattern in the same research program: a stronger felt bond with a media character tracks with how much a child learns from it, not just how much they enjoy it.

Wider Roads Can Make Traffic Permanently Worse

Setup. A city adds lanes to a jammed highway, expecting faster commutes. The Downs-Thomson paradox, named for economists Anthony Downs and John Michael Thomson, says that will not work alone. Equilibrium traffic speed is set by the door-to-door speed of the next-best alternative, usually the subway or bus, not by how much road space exists.

The argument. Widening the road pulls transit riders into their cars, thins transit ridership, and degrades the alternative that was keeping car speeds in check. "Any improvements in road networks lead to no alleviation of congestion, but usually more use of those roads." Economist Martin Mogridge documented this in a 1990 case study of London: each round of road expansion drew more driving, not less.

Where it stands. This is an equilibrium model, not a universal law, and it only bites where transit is a real substitute commuters would otherwise use. A related result, Braess's paradox, shows added capacity can reduce network performance directly, in computer networks as well as roads. That road capacity alone does not fix congestion is now standard among transport economists, though the effect's size in any one city stays hard to pin down.

Who Needs You Less Holds The Power

Setup. In any two-person relationship, power rarely splits evenly. Sociologist Willard Waller named the imbalance in 1938: whoever holds less emotional stake in a relationship controls it, because they can walk away at a smaller cost to themselves than their partner can.

The argument. "The person or group that has the least interest in continuing a relationship has the most power over it." Later studies tested the claim directly. A 1972 survey of 113 college students found men consistently less emotionally invested than women in the same relationships. A 1994 study of 413 heterosexual adults found the partner who felt less involved also held more say over shared decisions, including birth control.

Where it stands. The pattern replicates across decades and relationship types, including a 1984 study in which 40 percent of surveyed lesbian couples reported an unequal balance of power, always favoring the less-dependent partner. This is a structural observation about leverage, not a lab-tested causal mechanism, and the studies lean on small, self-selected samples. The same logic extends past dating into any negotiation: whoever can walk away more cheaply sets the terms.

No One Has Ever Catalogued the Human Drives

Setup. Chemistry became a real science once chemists listed the elements. The blog Slime Mold Time Mold argues psychology never did that for human motivation: nobody has tried to list every drive, hunger, fear, status-seeking, that pushes people to act.

The argument. "There are lots of drives that we haven't discovered, and the distinctions we have are totally informal." A single hunger drive cannot explain why people crave salt, sugar, or one food on one day, so several hunger drives tied to specific nutrients must exist. One contributor who craved iodine-rich seaweed snacks took iodine supplements for 27 days and reported that by day 18 the snacks tasted like dry plastic, as if a hidden iodine drive had switched off.

Where it stands. This is a research proposal dressed as an essay, not a settled finding, and one person's experiment proves little alone. The chemistry analogy is suggestive, not demonstrated: an element can be weighed, while a drive has no agreed test for existing at all. It is worth holding loosely, as a frame for noticing how little is known about why people want what they want.

ARCHITECTURE HISTORY · essayist's case study, documented funding dispute · Oct 2026

Ornate Architecture Dies From Fatigue, Not Just Cost

Setup. Art Nouveau, the swirling, plant-inspired style behind Gaudí's Sagrada Família, broke deliberately from centuries of copying older architecture and spread across Europe around 1890 to 1910. It vanished within twenty years, replaced almost everywhere by a return to classicism. An Asterisk essayist uses one building to ask why.

The argument. At Barcelona's Sant Pau hospital, archival records show a fight between leaders who wanted plain, fast-built wards and the patron's executors who wanted an architectural statement. "The latter group won, which is why there’s an architecture masterpiece in Barcelona that we can visit. However, this had the unfortunate consequence that some of the pavilions built later are less elaborate, because the project was running out of money." The essayist adds his own account: ornament produces a "wow" effect that fades into cognitive load, while classical architecture stays available as a style to return to.

Where it stands. The funding conflict is documented history, not speculation. The cognitive-load explanation for the style's decline is the essayist's own interpretation from visiting the buildings, offered without a controlled test, a plausible frame rather than a settled finding.
